| dc.description.abstract | In the process of exploiting the economic potentials of fish as a source of quality protein among others, adequate identification and characterisation of the diverse fatty acids components of the fish species is very necessary. Therefore, the fatty acids compositions of freshwater fishes (Hyperopisus bebe, Mormyrus rume, Mormyrops anguilloides, Oreochromis niloticus, Sarotherodon galilaeus, Clarias gariepinus, Clarias anguillaris, Heterobranchus bidorsalis, Lates niloticus, Clariheterobranchus and Hydrocynus forskali) was studied and compared with that of the twelve marine species. The fatty acids were determined by GC-MS and were identified using retention time locked methods and retention time databases. The fatty acids profiles include minor amounts of odd-number, branched-chain, and even-number fatty acids as well as saturated components, the MUFA and PUFA. The major SFA were C14:0 and C16:0. The C18:1 was the prominent MUFA. The dominant PUFA are of the Omega-6 series and are found chiefly in C18:2 fatty acids. The essential fatty acids compositions showed prominence in C18:3n-3 and C18:2n-6. The overall significance of this study was that the marine fish are better sources of Omega-3 EFA while freshwater fish are good source of Omega-6 EFA. The regular pattern of marine fish FA compositions makes them of advantage to the Hydrogenator. The high percent of branched and saturated FA in freshwater fish gives them an advantage in processing. A systematic review of the scientific medical literature was included, in order to appraise, and synthesize the evidences for the economic potentials accruable from these natural resources as regard their contents of EPA and DHA | en_US |
